B. Write an equation to represent this proportional relationship. Make sure to define the variables you use.

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.

step-by-step explanation:

$450 is the answer.

step-by-step explanation:

30% of 450 = 135
